Game Update 1.2 brought to players new crafted moddable weapons. These items can be made by Artifice and Armstech and as most of you already know, crit crafting results in an augmented item.
Some of the moddable weapons can be learned by the trainer, while others can be learned from schematics (obtained through Treasure Hunting and Investigation).
Treasure Hunting missions have a chance to yield Custom (orange) lightsaber schematics as a reward. Investigation missions have a chance of yielding Custom (orange) tech weapon schematics as a reward.
Here is a list of all crafted moddable weapons for both Artifice and Armstech. For the 3D models (ranged weapons only, since the lightsabers are..well..a handle with a color crystal ), click on the link below.http://www.oldrepublic.net/485-all-crafted-moddable-weapons-looks.html
